Hey yall. I have a 15.5 gallon stainless keg boiler with a 5500 watt/240 volt heating element with a ssr controller. The head is 2 inch diameter copper x 12 inches tall and a 30 inch condenser made from 1 inch copper pipe with 1/2 inch copper pipe inside. My question is if I add a dephlegmator, sight glass and 18 inch copper pipe between the 12 inch head and the keg will this work properly as a reflux still or should I just build a new shorter head to mount onto it to make a proper reflux still?.
